Do not get confused, as what happens has nothing to cause big problems. Your girlfriend loves you.
Now is the time to speak to her appreciating her role and always make her feel that she is brave. You want to do this, because the real problem that may face you both is yet to come.
Speaking about cultural and traditional barriers, I should say you should both try your best to shorten the gabs. You probably have some examples of marriages between different casts. Use these examples.
Let your girl politely convince her parents that marriages in the same cast could fail, as it has happened to her during the engagement. Let her stress on love and respect that build good families and even make specific cast wide with intermarriage relations.
However, you should both be very wise and polite here. At the same time, let your girl show much respect to her parents and yours.
Make her strong by your words, knowledge and open culture and always speak about your duties and responsibilities as new generation to bring good awareness to your society and rebuild new concepts for good integration in the entire Indian society.
